Binance hacker sells 908,793 PROM worth $5M for $71 on Uniswap V2
Before the sale, those same tokens carried a market value of about $5 million.
The sale took place on Uniswap V2 around October 31, 2026, according to the research findings. The wallet received 0.0316 ETH for the full PROM bag, worth about $71. The Uniswap V2 pool used for the trade was nearly empty, meaning very little ETH sat on the other side to absorb a sell of that size.
On Uniswap, the pool itself sets the price based on the ratio of tokens it holds. Dump a huge amount of one token into a shallow pool, and the price of that token craters with every unit you sell. Traders call that gap between the expected price and the actual fill slippage.
In this case, the slippage was extreme. A position valued at about $5 million came back as roughly $14 for every million dollars of paper value. The PROM sale doesn't stand alone.
